Pegged for greatness before they became teenagers, Venus and Serena Williams somehow lived up to, and even exceeded, the massive hype that surrounded them. Serena has the Open era record for most Grand Slams, Venus won five Wimbledons, the fourth most of any woman. They faced off in a staggering nine Grand Slam finals, including at the 2017 Australian Open when both were over the age of 35. In the 2000s, the sight of a Venus-Serena final was so routine that it seemed ordinary, as if two sisters from the same inner-city home, coached by a father who decided to put his daughters into tennis because of a tournament he saw on television, meeting in the finals of the biggest events in tennis - from Melbourne to Wimbledon to the U.S. Open - could ever be ordinary. Just as amazing is how well-adjusted the sisters are (minus the occasional Serena temper tantrum) after a lifetime of pressure and scrutiny.
